Legendaries are the "boss monsters" and while technically there are billions of possibilities from blending tertiaries together, I'm limiting myself to only 25 legendaries, as a neat bookend to the 25 primaries.
These are always huge and powerful and a mall "Catcher" can only own one of each at a time. CURRENT COUNT: 20
Comparable to legendaries are the unique monsters.
There is only one of each, they can only be obtained through very specific tasks and they cannot be blended into or out of, at least not by the traditional rules of blending... COUNT: 3
